C-s C-s... with no previous string

[Dan Jacobson]

Maybe emacs should say something if no previous string is known:
$ emacs
C-s C-s [C-s...]

At it is it feels like one has hit XOFF :-)

I agree.  Here's one way to do it:

*** emacs-20.7/lisp/isearch.el.orig	Wed May 31 05:43:30 2000
--- emacs-20.7/lisp/isearch.el	Thu Jan  2 11:12:27 2003

*** 906,912 ****
   		(or (if isearch-regexp
   			(car regexp-search-ring)
   		      (car search-ring))
! 		    "")
   		isearch-message
   		(mapconcat 'isearch-text-char-description
   			   isearch-string ""))
--- 906,915 ----
   		(or (if isearch-regexp
   			(car regexp-search-ring)
   		      (car search-ring))
! 		    (progn
! 		      (message "Search ring is empty")
! 		      (sleep-for 1)
! 		      ""))
   		isearch-message
   		(mapconcat 'isearch-text-char-description
   			   isearch-string ""))

Please, no!  I hate to wait for sleeps.  Use sit-for, so I can continue
editing at once.  Or better, temporarily append " [Search ring is
empty]" to the prompt, but I guess that's more work.
